WebbStructurally effective length of column is defined as height between the points of contraflexure of the buckled column i.e. between two floors basically. The effective length of column depends on whether the frame is sway or no-sway and on the bending stiffnesses of the beam meeting at the column. WebbThe following table lists the effective lengths for columns terminating with a variety of boundary condition combinations. Also listed is a mathematical representation of the buckled mode shape. In the table, L represents the actual length of the column. The effective length is often used in column design by design engineers.
